Soy protein market seen reaching $13.7 billion by 2033

Persistence Market Research valued the global soy protein market at about $8.6 billion in 2026 and projected it to climb to $13.7 billion by 2033, a 6.9% compound annual growth rate. The June 17 update cited soy’s complete amino acid profile, cost-effectiveness and broad functionality across food, beverage, nutrition and feed applications. Sports nutrition brands are using soy protein isolates in powders, ready-to-drink beverages, meal replacements and performance supplements.

U.S. Soy says soy protein is a complete protein that provides all essential amino acids in appropriate amounts for both children and adults. In the United States, soy’s regulatory history includes the FDA’s authorized health claim for soy protein and coronary heart disease, which dates to October 1999; on October 31, 2017, the agency proposed revoking that claim. Susan Mayne, then the FDA’s top food official, said some evidence continued to suggest a relationship between soy protein and reduced heart disease risk, but later studies produced inconsistent findings on LDL cholesterol. A qualified health claim would let qualifying language reflect the limits of the evidence if the rule were finalized.

A 2026 plant-based protein market overview ranked soy first in the segment because of its mature supply chain, neutral taste and broad functionality. Persistence Market Research estimated the broader plant-based proteins market at about $22.5 billion in 2026 and $38.1 billion by 2033.

A 2026 soy protein isolates market report valued that market at USD 4.47 billion in 2026 and projected it at USD 9.41 billion by 2034, while a soy protein ingredients report put Asia Pacific at a 45.65% share in 2025. Price and taste gaps remain persistent barriers in plant-based foods.
